A post-credits sequence in X-Men: Apocalypse and audio commentary on the film confirmed that Mister Sinister will be the villain in the sequel, but now Boyd Holbrook's character has also been confirmed with a stark Instagram image and a single word on director James Mangold's page.

The weathered Professor X fits with leaked info hinting that the X-Men founder's mind and powers are slowly fading away, leaving him to be cared for by Wolverine and Caliban (rumoured to be Stephen Merchant).

James Mangold's cast for Hugh Jackman's final Wolverine movie also includes ER's Eriq La Salle and Fear the Walking Dead's Elizabeth Rodriguez.

There have also been hints that Liev Schreiber could return to the X-Men series as Sabretooth.

Logan opens in cinemas on March 2, 2017 in the UK and March 3, 2017 in the US.
